The purpose of this study was to validate abuse outcomes included Nursing Outcomes Classification(NOC) developed by Johnson and Maas at the University of Iowa. A sample of 71 nurse experts working in university affiliated hospitals participated in this study. They were asked to rate indicators that examplified the outcomes on a scale of 1 (indicator is not at all characteristic) to 5(indicator is very characteristic). A questionnaire with an adaptation of Fehring's methodology was used to establish the content validity of outcomes. The results were as follows: 1. All indicators were considered to be 'supporting' and no indicators were considered to be 'nonsupporting'. 2. 'Abuse Recovery : Emotional' attained an OCV score of 0.780 and was the highest OCV score among abuse outcomes. The highest indicator was 'demonstration of positive interpersonal relationship'. 3. 'Abuse cessation' attained an OCV score of 0.739 and was the lowest OCV score among abuse outcomes. The highest indicator was 'physical abuse has ceased'. 4. 'Abuse Protection' attained an OCV score of 0.743 and the highest indicator was 'plans for avoiding abuse'. 5. 'Abuse Recovery: Financial' attained an OCV score of 0.762 and the highest indicator was 'court-ordered benefits received'. 6. 'Abuse Recovery: Physical' attained an OCV score of 0.767 and the highest indicator was 'resolution of physical health problem'. 7. 'Abuse Recovery: Sexual' attained an OCV score of 0.768 and the highest indicator was 'expression of confidence with gender identity'. More outcomes need to be validated and outcomes sensitive to Korean culture need to be developed.

고분자 전해질 연료전지(PEMFC) 고분자 막의 전기화학적 내구성을 가속적으로 평가하는 개회로 전위 유지(OCV holding) 과정에서 OCV 변화 거동을 해석하는 것은 매우 중요하다. 본 연구에서는 내구성이 각기 다른 세 종류의 MEA(membrane electrode assembly)의 실험데이터를 이용한 실험식을 만들어 비교 및 검토하였다. 막 내부에 라디칼 제거제가 없는 강화막 MEA의 내구 평가시간은 383 h, 막 내부에 라디칼 제거제가 있는 강화막 MEA의 내구 평가시간은 각각 1,000, 1,650 h이었다. 고분자 막의 열화는 활성화에 의해 회복이 가능한 가역적 열화와 회복이 되지 않은 비가역적 열화로 구분했다. 고분자 막의 비가역적 열화는 수소투과도 증가로 나타나는데 수소투과도 변화가 세 MEA 모두 비가역적 열화 상수 c와 유사한 형태를 보였다. 회복이 되지 않은 비가역적 열화가 시작되는 것은 수소투과도 증가로 나타나고, 수소투과도 증가로 인해 OCV가 회복되지 않아서 OCV 회복선의 기울기가 감소하고 이를 실험식의 상수 c 값의 증가로 확인할 수 있었다.
